Design and evaluation of a remote air-jet pneumatic stowing system.
Washington, DC: U.S. Department of the Interior, Bureau of Mines, AML 04-95, 1990 Jun; :1-51
During the early 1980's remote pneumatic stowing was advocated as a means to fill dry mines. Remote stowing was emphasized because some available methods required admittance of workers to the mine workings to operate the conveyance system, and many of the mine workings were not considered sufficiently safe for such procedures. The goal of this report was to further investigate a unique system known as the Remote Air-Jet Pneumatic Stowing System. This investigation included records of past performance, improvements to existing equipment, full scale field testing to develop operational parameters for equipment and materials, and recommendations for any needed modifications to the system to optimize performance.
